4 Claims. (o1. 198-200) The present invention relates to improvements inconveyer mechanism, and more in particular to novel structure in a chainconveyer such as used in hauling logs from a pond to the log deck of sawmills. l

Among the objects of the present invention is to provide a novelattachment for a chair or carriage to a link of a chain conveyer usedfor hauling or conveying logs in a saw mill, charac- Zerized as being ofsimplified construction with a minimum of parts and wherein the carriager dogs may be conveniently assembled or disassembled in respect to thechain, thus saving a considerable amount of time where this becomesnecessary because of worn parts needing replacement.

A further object of the present invention is to provide a novelconnection between the dog or carriage and the conveyer chain such asused .121 saw mills, which is free of separate or loose parts and whichis characterized by including a saddle on the carriage or chair adaptedto embrhce a link and interlock with a saddle seat orovided thereon, thesaid assembly being so constructed and arranged as to permit the saidcarriage to be readily inserted in place over the carriage seat andbeing held in its assembled interlocking relation by means of a pin,bolt or any other similar means.

Other objects, features, capabilities and advantages are comprehended bythe invention, as will later appear and as are inherently possessedthereby.

Referring to the drawing:

Figure 1 is a fragmentary view in elevation of a conveyer mechanismembodying the present invention;

Figure 2 is an enlarged view of a conveyer link and carriage embodyingthe novel structure of the present invention and disclosing the samesomewhat more in detail than shown in Figure 1 of the drawing;

Figure 3 is a view in end elevation of the assembly shown in Figure 2 ofthe drawing;

Figure 4 is a top plan view of the assembly shown in Figure 2 of thedrawing;

Figure 5 is a view in section taken in the plane represented by line5--5 of Figure 2 of the drawing; and

Figure 6 is a view in cross-section taken in the plane represented byline 66 of Figure 2 of the drawing.

Referring now more in detail to the drawing, a conveyer mechanismselected to illustrate the present invention is shown in Figure l of thedrawing as comprising a chain 2 formed of a plurality of interlockinglinks, one or more of which, such as the link 4, is of a particularconstruction and adapted to have secured thereto a carriage or chair 6.

The conveyer mechanism referred to is such as is used in conveying orhauling logs from the pond to the log deck of a saw mill, although it isto be understood that this invention may be embodied in other conveyersincluding link structure such as shown herein. The link 4 comprises amember formed with the opposed sides 8 and ID, with which is integrallyconnected a saddle seat or filler member l2 intermediate the ends of thesaid link. Said filler member is provided with the projections l4 and i6extending laterally beyond the planes defining the side edges of thelink which are adapted to be received in grooves l8 and 20,respectively, formed on the inner faces of depending legs 22 and 24 ofthe said carriage or chair 6. These depending legs 22 and 24 areconnected to the base 26 of the carriage which has integrally formedtherewith on its upper surface a plurality of marginal teeth or dogs,such as 28, and intermediate teeth or dogs such as 36, which form a seator support for logs resting thereon whereby the same are conveyed by theconveyer chain 2 from one point to another in the milling operations. 7

It will thus be seen that the base 26, together with the spaced legs 22and 24 of the carriage 6, provides a saddle embracing the link 4 andinterlocking therewith through the medium of the grooves l8 and 20 whichembrace the projections I4 and I6. In order to maintain this assembledrelation between the carriage and link, the said filler member l2, aswell as the depending legs 22 and 24, are provided with openingstherethrough slightly staggered in respect to one another to receive adrift pin, such as 32, which may be driven into wedging relation withthe elements of this assembly for holding the same in operativeposition. While the embodiment selected for the purpose of disclosingthe present invention embodies a drift pin, nevertheless it will bereadily appreciated that a bolt or any other element may be used for thesame purpose.

As will be readily appreciated, the particular construction for thecarriage 6 and the link 4 as hereinabove described for connecting thetwo together provides efiective means for interlocknew one with aconsiderable saving in time as compared to similar assembly jobs where anumber of loose pieces are required to effect the connection. The novelinterlock between the carriage and chain according to the present invention provides ample bearing surface for the carriage or dog to withstandthe forces to which the same are subjected during the hauling of logsfrom one point to the other in milling operations. By the simpleexpedient of maintaining a reserve supply of links and chairs, such as 4and 6, respectively, any repairs which become necessary can be readilyand easily accomplished by removing any defective link or chair andsubstituting another.

While I have herein described and upon the drawing shown an illustrativeembodiment of the invention, it is to be understood that the inventionis not limited thereto but may comprehend other constructions,arrangements of parts, details and features without departing from thespirit of the invention.

I claim:

1. In a conveyer for logs or the like, the combination of a carriagehaving spaced depending legs formed with opposed grooves, a chain havinga link provided with an integrally formed intermediate filler memberprojecting from said link and adapted to be received in said grooves,and means for securing said link and carriage in interlocked relation.

2. In a conveyer for logs or the like, the combination of a carriagehaving spaced depending legs formed with opposed grooves, a chain havinga link provided with an integrally formed intermediate filler memberprojecting from said link and adapted to be received in said grooves,said legs and said filler member having openings therethrough, and a pindisposed in said openings and in wedging relation to said legs andfiller member to hold said link and carriage in interlocked relation.

3. A link for a conveyer chain assembly having a carriage formed withspaced depending legs, said link comprising a loop member formed withoppositely disposed ends and sides, and a filler member intermediate ofand spaced from said ends and being integrally connected to said sidesand having shouldered portions projecting laterally of planes definingthe said sides adapted to be received in cooperative relation with saidspaced depending legs of said carriage.

4. In a conveyer for logs or the like, the combination of a carriagehaving spaced depending legs formed with opposed grooves, a chain havinga link provided with a filler member extending between and rigidlyconnected to the sides of said link intermediate the ends thereof, saidfiller member having portions projecting from said link and adapted tobe received in said grooves, said legs and said filler member havingopenings therethrough, and a pin disposed in said openings and inwedging relation to said legs and filler member to hold them ininterlocked relation.
